O2 Sensor off that bank has been replaced several times(as recently as 5,000 miles ago). Check engine comes on every once in awhile with the same rich code. I can't remember the exact code anymore, but it's been the same. I've lost O2 sensors and catalytic converters on the same side consistently. I just want to identify the problem and get it fixed.
